200106～200311我院应用美国AGA公司制作的新型Amplatzer封堵器关闭室间隔缺损(VSD)65例,本文通过封堵前心电图表现和封堵后心电图变化,从心电学角度评价VSD介入治疗的可行性和安全性。1对象和方法VSD患者65(男28,女37)例,年龄2～75岁,其中年龄≤14岁50例,年龄≥15岁15例,前者 200106 ~ 200311 In our hospital, 65 cases of ventricular septal defect (VSD) were closed by a new type of Amplatzer occluder manufactured by American AGA Corporation. This paper evaluates the feasibility of interventional treatment of VSD from the perspective of electrocardiography through the ECG before occlusion and after electrocardiography Sexuality and safety. 1 Subjects and Methods VSD patients 65 (28 males and 37 females), aged 2 to 75 years, of which age ≤ 14 years in 50 cases, aged ≥ 15 years in 15 cases, the former
